Sneezeweed, so named because the dried plant was once used as snuff, produces an attractive sulphur-yellow flower consisting of a central disc or ball ringed by triangular, edge-notched petals. Though the cute, winsome flowers make Sneezeweed a YNPN favorite, the plant can become unkempt later in the season, so position it in a back-yard spot. A good rain-garden candidate. Blooms August to October. Sun to part shade. Medium-wet to wet conditions. 3-5'.
